White House Press Secretary Jay Carney has confirmed the Obama administration is withholding documents sought by a Senate panel as part of their investigation into CIA torture and rendition.

Jay Carney: “Throughout this process, the administration has facilitated unprecedented access to more than six million pages of records. As we have discussed with the committee, during the course of the review a small percentage, a very small percentage, of the total number of documents have been set aside because they raise executive branch confidentiality interests.”

Tensions over the Senate panel’s report flared this week when panel chair Senator Dianne Feinstein openly accused the CIA of spying on Senate staffers and seizing material from their computers. Amid the row, the Senate voted Thursday to confirm Obama’s pick for the CIA’s new top lawyer. Caroline Krass previously served in a top post at the Justice Department.
